Espresso is the most demanding brew method. It concentrates every quality in a coffee - good and bad - into a 30-millilitre shot. The beans you choose matter enormously. So does the grind, the ratio and the extraction time. This guide explains what to look for and where to start. For the complete guide to choosing coffee across all brew methods, read How to Choose Coffee Beans: The Complete Buying Guide.
What makes a coffee bean good for espresso?
A good espresso bean handles high-pressure extraction - around 9 bars of pressure over 25 to 30 seconds - without producing harsh bitterness or unpleasant sourness. Beans best suited to this are medium-to-dark roasted, low in acidity and rich in chocolatey, caramel or nutty characteristics.
Origins from Latin America, particularly Brazil and Colombia, are commonly chosen for espresso because they produce the kind of sweet, low-acid and full-bodied profiles that hold up well under pressure and work with milk. The bean also needs to be freshly roasted. Stale beans produce flat, lifeless espresso regardless of how carefully you dial in the shot.
Does espresso have to be dark roast?
No. The idea that espresso requires dark roast is a legacy of commercial coffee culture, not a technical requirement. In specialty coffee, espresso is regularly made with medium-roast beans - and sometimes even lighter.
Darker roasts do have characteristics that suit espresso: lower acidity, heavier body and chocolatey bitterness that holds up well in a concentrated shot and cuts through milk. For home brewers without highly precise equipment, a medium-to-dark roast is more forgiving - it has a wider extraction window, making it less likely you will produce a sour or bitter shot from a small grind error. Very light roasts require significant precision to extract correctly and are best attempted once you have established confidence with your setup.
What grind size do I need for espresso?
Espresso requires a fine grind - much finer than cafetière or pour over. The grounds should feel like fine table salt or finer still. The extraction window is narrow: 25 to 30 seconds for a standard double shot, at a ratio of roughly 1:2 - meaning 18 grams of coffee in produces around 36 grams of liquid out.
If your shot runs through too quickly (under 20 seconds), the grind is too coarse. If it runs too slowly (over 35 seconds), the grind is too fine. A burr grinder with a wide range of settings is essential - blade grinders cannot produce the consistent, fine particle size that espresso extraction requires.
Can I use single-origin coffee for espresso?
Yes - though it is more technically demanding than using a purpose-built espresso blend. Single-origin coffees can be pulled as espresso, but they require careful adjustment of grind, dose and yield to avoid over-extraction of tannins or under-extraction of sweetness.
"We try to make the coffee simple as it is. We don't bring it as a juice - too many syrups, too much flavour, too much sweetness. The source of coffee should speak for itself."
- Ameen, Founder, Hamdan Coffee
The results, when well-executed, can be exceptional: a single-origin espresso from a well-suited origin - particularly Colombian - can be intensely sweet, complex and unlike anything from a traditional espresso blend. Colombian single origins tend to work particularly well in espresso: naturally lower acidity, good body and a sweet, chocolatey character that translates cleanly under pressure.
Why are Yemeni coffee beans better suited to filter brewing than espresso?
Yemeni coffee beans - particularly naturally processed single origins like Royal Haraaz - are characterised by intense dried fruit, wine-like complexity and a thick, syrupy body. These qualities shine through filter and pour over methods, where slow extraction allows the full flavour profile to develop clearly.
Under espresso's high-pressure extraction, the intensity of naturally processed Yemeni beans can result in a shot that is overwhelming or unbalanced without very precise dialling in. The complex, fruit-forward character that makes Yemeni coffee exceptional in a V60 or cafetière is also what makes it harder to manage in an espresso machine.
This is not a quality problem - it is a compatibility question. Yemeni coffee is most at home as filter. That is where it gives the most.
What espresso coffee does Hamdan Coffee recommend?
Hamdan Coffee stocks Colombian beans specifically chosen for espresso drinkers. Colombian coffee produces a naturally low-acid, full-bodied cup with caramel, chocolate and mild fruit characteristics - well suited to high-pressure extraction and easy to work with across a range of home machines.
For drinkers who want to experience Yemeni coffee but prefer espresso as their everyday method, the Bedouins' Brew is a finely ground traditional Yemeni preparation that suits stronger, concentrated serving styles - though it is intended primarily for traditional methods rather than modern espresso machines.
For straightforward espresso at home, the Colombian beans are the most reliable starting point.
